“…However, eggs can supply many other important nutrients, plus vitamin A, for human beings. Liberato & Sant'ana (2006) performed a study in Guatemala in order to achieve the recommended daily intake of vitamin A by people with high risk of deficiency of this vitamin and concluded that the per capita costs for enrichment was US$0.98; for the distribution of capsules was US$1.68 to US$1.86; and for programs of nutritional education that motivated the making of vegetable gardens was between US$3.10 to US$4.16. Retinol supplementation has no relation to the levels of cholesterol in eggs, therefore it is possible to produce enriched feed that promote beneficial effects to health without unfavorable side effects.…”

Effect of supplementation of diets for quails with vitamins A, D and E on performance of the birds and quality and enrichment of eggs

et al. 2011

-The objective of this research was to evaluate the performance of birds and the quality and enrichment of eggs from quails fed diets supplemented with vitamins A, D and E. Three experiments were performed, one for each vitamin, under completely randomized experimental design, with six replicates and eight birds per plot, totaling 192 quails. Performance of birds was evaluated by the daily feed intake, egg weight, laying percentage (%) and food conversion, per kg and dozen of eggs. It was also evaluated the internal quality (Haugh unit, yolk index and yolk and albumen percentages) and external quality (eggshell percentage, egg specific gravity, eggshell thickness and weight) and the concentration of vitamins in egg yolk by using the high performance liquid chromatography method. Vitamins supplementation did not improve productive performance neither the internal and external quality of the eggs, except for vitamin D supplementation, which increased intake.Incorporation of vitamin A in yolk increased 536.27% at level 30,000 UI/kg, vitamin D increased 13.43% at 1,500 UI/kg and vitamin E increased 479.05% at 600 UI/kg, and these results evidence that the nutritional value of eggs, related to vitamins, can be increased through supplementation of diets for quails.Key Words: cholecalciferol, Coturnix corturnix japonica, retinol, tocopherol Efeito da suplementação de dieta de codornas com vitaminas A, D e E sobre o desempenho das aves e a qualidade e o enriquecimento dos ovosRESUMO -Objetivou-se nesta pesquisa avaliar o desempenho das aves e a qualidade e o enriquecimento de ovos de codornas sob suplementação com vitaminas A, D e E. Foram realizados três experimentos, um para cada vitamina, em delineamentos inteiramente casualizados, com seis repetições e oito aves por parcela, totalizando 192 codornas. O desempenho das aves foi avaliado pelo consumo diário de ração, peso dos ovos, porcentagem de postura e conversão alimentar, por kg e dúzia de ovos. Também foram avaliadas a qualidade interna (unidade Haugh, índice gema e porcentagens de gema e albúmen) e externa (porcentagem de casca, peso específico, espessura e peso da casca) e a concentração das vitaminas na gema dos ovos, mediante o método de cromatografia líquida de alta eficiência. A suplementação das vitaminas não melhorou o desempenho produtivo nem a qualidade interna e externa dos ovos, com exceção da suplementação de vitamina D, que elevou o consumo. A incorporação de vitamina A na gema aumentou 536,27% no nível de 30.000 UI/kg, a de vitamina D 13,43% no nível de 1.500 UI/kg e a de vitamina E 479,05% no nível de 600 UI/kg, e isso evidencia que o valor nutricional dos ovos, relacionado à vitamina, pode ser aumentado com a suplementação na dieta das codornas.Palavras-chave: colecalciferol, Coturnix coturnix japonica, retinol, tocoferol Revista Brasileira de Zootecnia

“…Total fish consumption was calculated at a national population level as the sum of food supply quantity for each of the fish types [22]. Existence of vitamin D fortification policies per country (yes/no) was obtained from a 2006 review [23]. We calculated the average degree of skin pigmentation for each country, based on the 2006 WHO Solar Ultraviolet Radiation report [25] that categorised the population of each country proportionally into light, medium, or deep skin pigmentation, based on race or ethnicity information of each country, using the Fitzpatrick skin tone chart (table 1).…”

Epidemiological evidence supports vitamin D deficiency as a risk factor for tuberculosis. Differences in solar ultraviolet B (UV-B) exposure, the major source of vitamin D, might therefore partially explain global variation in tuberculosis incidence.In a global country-based ecological study, we explored the correlation between vitamin D-proxies, such as solar UV-B exposure, and other relevant variables with tuberculosis incidence, averaged over the period 2004-2013.Across 154 countries, annual solar UV-B exposure was associated with tuberculosis incidence. Tuberculosis incidence in countries in the highest quartile of UV-B exposure was 78% (95% CI 57-88%, p<0.001) lower than that in countries in the lowest quartile, taking into account other vitamin D-proxies and covariates. Of the explained global variation in tuberculosis incidence, 6.3% could be attributed to variations in annual UV-B exposure. Exposure to UV-B had a similar, but weaker association with tuberculosis notification rates in the multilevel analysis with sub-national level data for large countries (highest lowest quartile 29% lower incidence; p=0.057).The potential preventive applications of vitamin D supplementation in high-risk groups for tuberculosis merits further investigation.

“…The sample that had the highest vitamin A content (44,000 IU/kg) more than the recommended value might suggest poor quality control measures in the fortification dosing process or addition of excess overage (Omar, 2005;Liberato and Pinheiro-Sant'Ana, 2006). Figure 2 shows the post-storage vitamin A stability losses in wheat flour samples.…”

“…Measures to provide quality control are necessary to guarantee food fortification in pre-established concentrations. Great variation was found in the concentration of vitamins as pre-established on the labels (Liberato and Pinheiro-Sant'Ana, 2006). A serious problem is measuring errors in the vitamin doses used for fortification during food processing (Liberato and PinheiroSant'Ana, 2006).…”
